WebApr 1, 2024 · The Mediator kinase module is conserved among eukaryotes, but paralogs for CDK8, MED12, and MED13 emerged in vertebrates (Figure I).Each paralog is expressed on different chromosomes and appears to be mutually exclusive within the kinase module [52].Comparatively little is known about how these paralogs function, but connections to … The protein encoded by this gene is a member of the cyclin-dependent protein kinase (CDK) family. CDK8 and cyclin C associate with the mediator complex and regulate transcription by several mechanisms. CDK8 binds to and/or phosphorylates several transcription factors, which can have an activating or inhibitory effect on transcription factor function. CDK8 phosphorylates the Notch intracellular domain, SREBP, and STAT1 S727. CDK8 also inhibits transcriptional activation by in…
WebContext-specific functions of the CDK8 module: The primary area is in elucidating the context-specific roles of the CDK8 module, a highly conserved module of the transcription cofactor Mediator complex, which bridges DNA-bound transcription factors and RNA polymerase II (Pol II) in eukaryotes. WebFeb 3, 2014 · This suppression effect was attributed largely to the kinase function of Cdk8, as coexpression of kinase-inactive CDK8 (D290A) with MED3 did not abolish FLO11 expression; rather, expression was maintained at ∼40% compared with MED3 alone (Fig. 1B). These data imply that the activation potential of Med3 is suppressed by Cdk8 …
